Chuck, Jorgen
I just got done talking with John Pruner for over an hour. Great guy, very knowldgeable and absolutely no pressure. Given that I don't have a trailer I will change wheels/tires and drive < 400 miles to an event. So that limits me to tires that I can do highway driving on. The 18" Toyos and Michelin Pilot Sport Cups will work but we're talking about $1200 - $1400 a set. Kuhmo makes a nice sticky track tire that can be driven on the street as well. They're the Ecsta 712's but they only come in 17" (but they cost $700). One option is to get a used set of 17" wheels. These can be had for a song. John recommends getting 17x12 in front and 17x13 in back. This way you can run 335s all the way around. The only down side I can see with 17" wheels is that you can't go with a big brake kit. Of course you can always upgrade the rotors and go with slotted or drilled 13".
As far as the issue at Viper Days, I'm not aware of this except there was a fair amount of politics at one point and John decided to pull out. When you buy John's wheels you buy direct and that is probably the main reason for the lower cost. And they are made in lovely Daytona, FL. The SSR's are made in Japan and are $2216 from Tirerack. I can get them in town here in Albuquerque for the same price.
My dilemma is whether to get new wheels with track/road tires for about $3600 or a used set of 17" wheels and new track/road tires for $1700.
